int priv_getbyname(const char  *priv, int flags);

INTERFACE LEVEL

DESCRIPTION

The priv_getbyname() function maps a privilege name to a privilege number for use with the priv_*() kernel interfaces.

If PRIV_ALLOC is passed as a flag parameter, an attempt is made to allocate a privilege if it is not yet defined. The newly allocated privilege number is returned.

Privilege names can be specified with an optional priv_ prefix, which is stripped.

Privilege names are case insensitive but allocated privileges preserve case.

Allocated privileges can be at most {PRIVNAME_MAX} characters long and can contain only alphanumeric characters and the underscore character.  

RETURN VALUES

This function returns the privilege number, which is greater than or equal to 0, if it succeeds. It returns a negative error number if an error occurs.  

ERRORS

EINVAL

o The flags parameter is invalid.

o The specified privilege does not exist.

ENOMEM

There is no room to allocate another privilege.

ENAMETOOLONG
